The New York City subway has long served as a makeshift gallery for budding and well-established visionaries, but a group of artists is taking it one step further by utilizing another transit-affiliated canvas for their works: MetroCards. As part of a two-day exhibition, “Single Fare,” now in its fourth run and taking place in the Meatpacking District, artists are reimagining the MTA’s iconic transit passes into installations, paintings and more.

Jean-Pierre Roy, one of the creators of the exhibition, tells The New York Timesthat the “only real constraint”was to create a work of art either on a MetroCard, or using one. Artists have taken this creative liberty to put together a variety of unique works — covering the MetroCard entirely or in part with tiny paintings, or constructing complex sculptures. In the past, cranes, trains and chandeliers have been crafted; portraits and landscapes have been drawn and detailed cut-outs, which cast shadows, have been painstakingly crafted. (Our favorite is this one of Yoda.)

The Single Fare Facebook page explains where the idea for the show came from: “Inspired by the notion that the city’s subways and buses allow for a kind of creative interchange unmatched in human history, the first ‘Single Fare’ sought to create a unique art event where art and artists could come together to form a monumental event made from a tiny, innocuous piece of plastic: The MetroCard!”

This year, over 3,000 projects were submitted for consideration when Jean-Pierre Roy and Michael Kagan, the other “Single Fare” creator, put out an open call for artwork. To see the pieces in person, pay a visit to Highline Stages on West 14th St. this weekend from 5 to 8PM on Saturday and noon to 6PM on Sunday.
